Heat exhaustion is the cause of death of a Brazilian fan who attended a concert of singer Taylor Swift in November, a forensics report obtained by The Associated Press on Wednesday shows.

Ana Clara Benevides, 23, passed out during Swift's second song in the Nov. 17 concert in Rio de Janeiro, "Cruel Summer," and died hours later at a local hospital. Temperatures in the city that day were at about 40 degrees Celsius (105 Fahrenheit).
